Specification of Letters Patent.

Application filed November 24, 1914. Serial No. 873,688.

To all whom it may concern Be it known that 1, CHARLES C. Bons- WALD, a citizen of the United States, reslding at No. 604- East Fifteenth street, New York city, in the county of New York and State of New York, have invented a new and useful Window-Screen, of which the following is a specification.

My invention relates to improvements in window screens by which the entire window is covered on the outside; and the objects of my improvements are, first, to provide a window screenin two parts, with an extension rail to screen a window perfectly tight on the outside of the window, and second, to afford facilities for the adjustment and re moval of the same from the inside of the window to permit access to the outside of the window. I attain these objects by means illustrated in the accompanying drawings, in which Figure 1 is a plan view of the entire window screen in position. Fig. 2 is a sectional view through line IX-13 of Fig. 1. Fig. 3 is a sectional view through line CD of Fig. 1. Fig. 4 is a perspective view of the entire window screen in position, embodying my invention. Fig. 5 is a perspective view of stop beading, head rail and extension rail in an assumed position. Fig. 6 is an enlarged sectional view of stop beading G. Fig. 7 is an enlarged sectional view of extension rail H. Fig.- 8 is an en larged sectional view of head rail E.

Similar letters refer to similar parts throughout the several views.

The blind-stop casing A and window sill B constitute the framework of the window. All of this part of the construction is old and well known, and needs no especial description.

G and D are the upper and lower parts of the window screen respectively.

E is the head rail; F extension rail;

# Gr stop beading; H beveled rabbet joints; J pins; K rabbet on stop beading for window screens; L rabbet on stop beading to connect on to the blind-stop casing; M dimension of stop beading between rabbets K and L.

I prefer to carry out this feature of my invention in the following manner by providing a stop beading for each side of the window which is fastened to the blind-stop casing with small nails. This stop beading shown by the letter G has two rabbets,

one to connect on to the blind-stop casingshown by the letter L, the object of this rabbet is first, to act as a guide for the blind-stop casing to fit in and second, to make a tight joint with the blind-stop casing. The other rabbet on the stop beading shown by the letter K is for the entire window screen to rest in when in normal position. On top in this rabbet and nailed to the blind-stop casing is the head rail shown by the letter E. This head rail has a beveled rabbet which forms with the top rail of the upper screen a rabbet joint shown by the letter H. The object of this head rail is to hold the top of the upper screen in position. The same rabbet joints shown by letter H are between the lower rail of the upper screen and the top rail of the lower screen, and the lower rail of the lower screen and top of the extension rail. The object of these rabbet joints are first, for the top rabbet of each joint to hold the lower rabbet in each joint in a firm position, second, to form a close joint and prevent opening from warping or loose fitting and third, to hold the entire window screen in one straight vertical plane when in normal position. The upper screen is held in position by its upper rail locking itself into the head rail and the lower part is fastened with any suitable wire pin on each side shown by the letter J. These pins are inserted into holes bored through the side of the screen and into the stop beading.

The extension rail is shown by the letter F and is set in loose, then the lower screen is inserted which looks its upper rail into the lower rail of the top screen, and the lower rail of the lower screen locks the rabbet of the extension rail. The lower screen is also fastened with pins shown by the letter J. The object of the extension rail is to reduce the vertical dimension between the blind-stop casing and the window sill so that when the screen is made of two equal parts in height in conjunction with the extension rail, they will pass through the clearance space of the lower window sash when both window sashes are pushed up to their extreme height. The dimension of the stop beading shown by the letter M reduces the horizontal dimension between the blind-stop casing so that when the screen is made to fit said dimension between the stop beading they will pass through the clearance space of the lower window sash when both window sashes are'pushed up to their extreme height.

By making the screen in two equal parts in conjunction with the extension rail to cover the vertical dimension and of the size to cover the horizontal dimension between the stop'beading, they can be conveniently inserted and removed through the clearance space of the lower window sash when both window sashes are pushed up to their extreme height. t

Having thus described my invention, what I claim is: U

1. The combination in a window frame, the side members of the blindstop-casing with stopbeading, the top member of the blindstop-casing with head rail, and the window sill with extension rail, a screen composed of two equal sections, each less in height than one half the space between window sill and blindstop-casing in height, but capable in conjunction with the head and extension rails to cover the entire window in height.

2. The combination in a window frame, the side members of the blindstop-cnsing with stopbeading, the top member of the blindstop-casing with head rail, and the window sill with extension rail, a screen composed of two equal sections, less in width than the space between the blindstop-casing in width, but of a size that in conjunction with the dimension of the stopbeading will cover the entire window in width.
